One of my mods works fine with RML, but causes a NullPointerException to be thrown when loading a world with FML. (I haven't tried to reproduce this though. This is a problem someone else was having).

 

The "ForgeModLoader-client-0.log" is here.

 

The code that causes the crash is:

public void clientConnect( NetClientHandler client )
{
	enabled = false;
	client.addToSendQueue( new Packet250CustomPayload( "SC0|SGCheck", null ) );
}

 

And the mod in question is here.

 

Am I missing something?

 

(I hope I gave enough information, and that this was the right place to post this. )

Heh, that's a result original. But NPE shouldn't happen with the code you quoted..
